| 摘 要： | 本文对Ｍａｒｇｕｌｅｓ方程，ＶａｎＬａａｒ方程和Ｗｉｌｓｏｎ方程预测二氧化碳／正丁烷、二氧化碳／异丁烷体系在２５０～２８０Ｋ温度范围活度系数的精度作了比较。１４１个数据点的计算结果表明，Ｍａｒｇｕｌｅｓ方程显著优于ＶａｎＬａａｒ方程和Ｗｉｌｓｏｎ方程。

| Abstract: | Comparisons are made between accuracies of activity coefficent for carbon dioxiden-butane and carbon dioxide-i-butane binary systems at 250-280 k calculated from Margules,van Laar and Wilson equations. Results from 141 data points show that Margules equation is much better than both van Laar and Wilson equations. |
